Jim Barbee, chief of the Control Board’s technology division, said the key — known in the industry as a 2341 key — is a common tool used by slot machine technicians to gather information or reset a game following verification of large jackpot. Most keys are generic and work on slot machines of all manufacturers.

Using the key doesn’t allow access to a slot’s inner workings and won’t change the outcome of a game.

“The key gives the technician access the device’s program information,” Barbee said. “The key allows you to read that information. It’s a generic key in the industry.”

It’s also an item available to the public, but not through normal channels. A check on eBay.com found more than a dozen listings for a “slot machine reset key” or a “2341 key” for several manufacturers, including International Game Technology, Bally Technologies and WMS Industries. Prices ranged from $2.99 for a single key to nearly $100 for 72 keys.

Does the Wizard have a key for evaluation purposes? (Probably wouldn't go over too well, I expect). Is it something you can only use when the machine is already open?
